Similar numerals refer to similar parts throughout the several views.

The votometer usually consists of three units or sections, for registering the aye, not-voting and nay votes, although it may be built to contain as many sections as there are different classes of votes to be recorded.

Each unit or section of the votometer consists of a projecting machine, in one adaption of my invention, such as shown generally in Fig. 9, in which a continuous film such as 50, or Si, or 52, or some equivalent thereof such as a 'glass disc or drum containing consecutive vote numbers, is rapidly moved or rotated from one position to another, to display the totals. In Fig. 1 three such units or sections are placed within a single box 53, and their vote totals are displayed on the screens 50a, 5Ia, and 52a. A side view in section form of this arrangement is illustrated in Fig. 2, wherein bracket 55 holds the mirror 55 in position to reflect the beam 56 to its associated screen. Light guard 51 protects the image from overhead light.

In Fig. 3 a mounting is shown, desirable when a larger image is required. Steel wall box 58 contains a system of mirrors 59, 60 and GI, for enlarging the beam within a small space, and refleeting it to screen 62 under visor 51. Bracket 58a acts as a shield for separating the light beams besides supporting mirrors 59 and BI, and it will be seen that the projecting lenses are mounted vertically.

Projection may be secured without mirrors, as shown in Fig. 4, by attaching a front plate 83, holding light-horn 6G and screen 65, to steel box 66. v

The assembly illustrated in Fig. 1 may be placed on the floor under the presiding omcers desk, as shown in Fig. 5, if he alone is to read the results. Or by using vertical lens such as indicated at 61 of Fig. 5, the image may be projected on miniature screens on top of the presiding oilicer's desk 80. If a miniature indicator board is used on the presiding officers desk, which is usually made by assembling telephone lamp jack strips 69 in a steel box 10 under brass trim 1|, the brass trim may be arranged to accommodate the small screens indicated at 12, thereby combining the totaling and indicating mechanisms in a single unit. Of course the screens 12 may be mounted separately from the indicator board 09, 10, 1|, if so desired. Furthermore screens 12 of Fig. 5 may be equipped with visor 13, and if it is desired visor 13 may be equipped with mirror 14, and screens 12a may be substituted for screens 12, thus refiecting the light-beam to the presiding officer.

Instead of displaying the results to the members by separate totalizer units such as shown in Figs. 2, 3 and 4, the principle of displaying the totals on the indicator board as disclosed in Fig. 5,

may likewise be applied to the large size indicator boards. Fig. 6 discloses a front view of a.

large indicator board containing votometer units. The doors, such as 15, are hinged to the frame as indicated at 16, within the metallic trim 11. Each door'has attached to it a series of card slots 18 having flanges 19 holding cards 80. Each card slot 18 is attached to the door by aye lampcap BI and nay lamp-cap 82. Somewhat matching the card slots 18, the screen holder 83 with its visor 84, and holding screen 85, is bolted at 86, to each desired door 15.

Fig. 7 gives a side view and Fig. 8 gives a top view of the indicator board and total display mechanism shown in Fig. 6. The trim 11 is fastened to steel wall box 81 which contains a votometer projecting unit 99 with vertical lenses 61 behind each desired door 15.

In a structure such as shown in Figs. 6, 7, and 8-, provision must be made to isolate the light of each lamp so it can shine only through its own lamp-cap; and provision must likewise be made to isolate the totalizing beam arising from each projecting lens unit 61. This is accomplished by attaching to the rear of each door 15 a channel member 89, which separates the rows of aye and nay lamps, and isolates the totalizing beam. The top of each channel member 89 is fitted with a mirror for reflecting the beam to screen 85. Bent metal light shields 9| are attached by every or every other lamp-cap such as 82. Glass lamp-caps such as BI and 82 may be fitted with spun metal holders, such as'shown at 92, which will serve to fasten card slots 18. channel member 09 and bent metal light shields, to door 15.

Of course channel member 89 could be fastened to steel box 91 instead of door 15, which would equally well isolate beams from projecting lens 61, but that construction would take away from door.

15 the desirable reinforcement strength found in channel 39. The indicator board lamps 93 may be fastened either to box 81 or to channel member 89 as shown.

Before discussing the mechanical action of the votometer let us refer to Fig. 9. An aperture covered by a mirror set at forty-five degrees to the frame is indicated at 94, permitting light from the projection lamp on the far side of the machine to pass through condensing lens 95 and film 50' or 5| or 52, and projecting lenses 61. to whatever type or screen may be used. A fllm track and lens housing indicated at 99, guides the film through its proper path between the lenses.

Adjustment for centering the image on the screen is provided by thumb screw 91, which holds lever 98 in any adjusted position, to frame 99. By loosening thumb screw 91, handle I00 of lever may be moved and looked as desired, causing lever roller IN to move film up or down.

The usual sprocket wheel and rollers for actuating the film are found at I02 and 103 respectively, and the usual spring arm rollers for putting light tension on the film, are indicated on both sides of the sprocket wheel, at I04 and I05 respectively. Shown at I20 is a governor, in this case in the form of an air paddle wheel, which. rapidly rotates when the film is in motion, and controls the speed of film movement.

The sprocket wheel I02 is capable of quickly moving the film to the desired display number, or restoring it to the zero or normal position. With the three-storage-unit votometer illustrated, the film or equivalent is moved to the desired display number in not more than three movements, and is restored to normal or zero in ion sleeve @222 shown in Fig. 31.

one movement. The mechanism for accompanying this will be described.

A totalimng shaft I01 runs entirely through the votometer, as shown in Figs. 14, 15 and 24, and is supported by bearings I08 and I09. Bolted and pinned to one end of shaft I01 at I I and I I I is a stop arm H2 which revolves with shaft I01, as shown in Fig. 29. A portion of the shaft I01 adjacent to bearing I09, is threaded at H3, and a travelling nut I I4 is engaged with these threads, and moves stop pin H5 attached thereto, out of path of stop arm I I2, when shaft I01 commences to rotate to set up a total. Steadying pin H6 is also attached to nut I I4 and moves through bearing M as stop pin H5 does, when shaft I01 rotates, but steadying pin I I 6 does not act as a stop.

Except for the small portion of the shaft I01 that is shown threaded at H3, all the rest of the shaft I01 that lays between the bearing blocks I68 and i053, contains gear teeth in the nature of a pinion rod, as indicated at I2I in Figs. and 24.

Fasteneci to shaft I01 is the gear wheel H1, best seen in Fig. i i, which drives pinion M8 on governor shaft M9 that supports paddle E20. Film breakage and excessive wear is overcome by using a governor. Gear wheel I H is fitted with a double ireyway to match the end keys E23 on pin- Figs. and 3 show how gear wheel Hi1 and pinion sleeve I532 are both attached by pin lift on turned shoulder of shaft MW.

A spring of the clock spring type shown at 625 in Fig. 15, having its inner end pinned to stub shaft iiiEi. and its outer end pinned to housing M1, at its, furnishes power to gear wheel iEii, through shaft flange iilfi to. which it is pinned, for

restoring shaft till to its normal position aftereach display of a total. A. spring housing 021 forms a bearing for one end of shaft I26, and the other end of shaft I26 is supported by bearing 689. Spring 025 may be adjusted for a stronger or weaker tension by removing screws I32, turning the housing ii'l until the desired tension is attainecl, and then replacing the screws I02. In 9 the shoulder of spring housing I21 is shown projecting through frame 99, and the four holes indicated in 9 at 633 are designed to receive a special tool for rotating spring housing I21 when screws I32 are removed for adjustment.

In Figs, 10, ii and 12 it will be observed that two numbers are applied to each frame in the film, and one set of sprocket holes is used for each frame. In Fig. 9 it will be seen that sprocket wheel I02 possesses eight teeth, and hence moves the film sixteen counts per revolution. In Figs. 1'7, 21 and 22 it will be seen that the pinion toothed portion I2I of shaft I0! is equipped with sixteen teeth. This means each time shaft I01 is rotated the distance of one tooth a new number is displayed.

In Fig. 13 the cover or housing for the projecting lamp is indicated at I34, and in Fig. 23, which is drawn in section, the projection lamp is shown at e, the reflector at I36, apertures for passing the beam at I31, I38 and I38. The beam then strikes reflecting mirror and condensing lens combination 94 and 95, and passes through film 50 or 5I or 52, and projecting lens 61 to the screen used, as previously outlined. 7

Spring I25 causes a stop arm H2 to abut stop pin II5 when shaft I01 is in its normal or zero registering position; which means spring I25 is wound up when totalizing shaft I01 is rotated for V registering a total. Spring I25 is capable of permitting shaft I01 to rotate against its pressure for several revolutions, and then spring I25 is capable of driving totalizing shaft I01 back to its normal or zero registering position where stop arm H2 abuts stop pin H5. Stop pin H5 is withdrawn from the path of stop arm I I2, by nut H4 during the first revolution of shaft I01, and stop pin H5 returns into the path of stop arm H2 only after spring I25 has driven-shaft I01 back to a position within one revolution of its normal position. Thus shaft I01 can rotate several revolutions from its normal position, moving the film. the full length of the number track, and then shaft I01 can be returned to its normal positionby action of spring I25, which restores the fllm to its zero indicating position.

The balance of the mechanism for each votometer unit consists of a number of devices called storage units, each capable of rotating shaft IIl'i, within certain limits, against, action of spring I25; and a magnetically operated looking and centering bar for holding shaft iii? in the advanced or vote registering positions against action of spring E25.

In the present application the votometer described possesscs three storage units. although any desired number of storage units may be used. These three storage units are indicated at aa, oh, and cc, in Figs. 13, 14-, 23, and These three storage units are identical mechanically, and only one of them needs description.

In Fig. 13 section lines ii, iii and E223, and Figs. i7, 21 and 22 corresponding thereto, illustrate a side view of e. storage unit. The storage unit is built upon two frame members, one of which is shown at Mil in Figs-25 and 26. The other frame member is similar thereto except the ear is bent in the opposite direction. These two frame members are shown in Figs. 23 and 24, as well as in Figs. 17, 21 and 22, to be pivoted on a short shaft Mi, mounted in bearing block 9 Each bearing block M2 is attached to frame plate its by shank I340 and nut i i-5. frame members N0 of each storage unit, besides being pivoted at Mi, are joined together by a screwed on bacit plate M6, and by a screw and bushing best illustrated at it! and M8 in Fig. 24. This frame work of each storage unit is normally held up by springs M5, which are attached to plate H58, but this frame work is capable or" being pulled downwards by the square headed solenoid plunger 50. pivoted between the frame members M0 by pin 55L when its respective solenoid i52 or I353 or i5 is energized. The square headed plungers I50 are equipped with shanks E55, upon which are held silencing washers I56, which deaden the noise when square heads of plunger-s I50 are returned to their normal position, determined by stop plate I51.

The frame work just described for each storage unit, contains as its principal operating element, as best shown in Figs. 17, 21 and 22, a gear wheei I59, to either side of which is attached by screws or rivets I60, a ratchet wheel I6I and I62. This gear and double ratchet combination is keyed at I63 to shaft I64. The shaft I64 also contains at each end, as shown in Fig. 20. a milled spring hook I68. Two spring housings. such as illustrated at I65 in Fig. 18, each containing a clock spring I66, having its outer end pinned to its respective housing at I61, and the two inner ends held to shaft I54 by the hooks I68, are attach d to frame members I40 by screws indicated at I09. A plate IBM for enclosing the spring I66 is placed The two 166, which provides for I66 that furnish the power for returning shaft I64 with the gear and ratchet wheel combination keyed thereon, back to its normal position. And when storage unit shaft I64 is restored to its normal position by springs I66, the gear is in mesh with shaft I01, and advances the film. During advancement of the film by resetting of storage unit, the two springs I66 are, in unwinding, causing main shaft spring I to become wound, aided by a favorable gear ratio for this purpose.

Two pawls are provided for each storage unit, the near pawl I10 illustrated in Figs. 17 and 21, acts as a holding pawl, and is pivoted at "I to an adjustable bolt I12, attached to the back plate I46. Spring I18 holds pawl I10 in contact with ratchet'wheel I6I.

Directly behind the holding pawl I10 just described is the operating pawl I14, best illustrated .in Fig. 22. Pawl I14 is pivoted at I15 to operating lever I16, and held in contact with its respective ratchet wheel I62 by spring I11. The operating level I16 is pivoted on the same shaft I4I that pivots the two frame members I40, and normally is held against adjustable stop screw I16 by spring I16. Operating levers such as I16 have pinned to them at. I84 solenoid plungers such as I83, and are actuated by solenoids such as I80 or I6I or I62. The stationary cores of all solenoids used on the votometer, including cores I81 of solenoids I80, I8I and I82 are threaded into base plate I65 and locked by a nut such as adjustment.

The adjustable core I61 of'each storage unit and the adjustable stop screw I16 thereof, provide the necessary adjustable stops for the proper movement of operating pawl I14. These stops are adjusted so operation of solenoid I60 or I6I or I82 will move the ratchet and gear wheel combination connected therewith, against the action of the two springs I66 connected thereto, for the distance of one gear or ratchet tooth, whereupon it is caught and held by the holding pawl I10. Both ratchet wheels IN and I62 have the same number of teeth, and each small tooth thereon corresponds to a gear tooth on the gear wheel I56.

It will be seen that each ratchet wheel i6I and I62 possesses a long tooth, I68 and I66 respectively.

After solenoid plunger I68 of each storage unit has by its repeated operation advanced the ratchet and gear wheel combination I56, I60, I 6i and I62 connected therewith, one step or tooth forward for each actuation, and after this operation has been completed in all storage units, the gear wheels I56 are consecutively brought into mesh with main shaft I01, by movement of each plunger I50, as solenoids I52, I58 and I54 are consecutively energized.

As each storage unit is pulled downward by its respective solenoid I52, I58 and I 54, the pawls on it I10 and I14, strike adjustable throw-out screws I60 and I6I, mounted upon bar I06, and by the time the gears are fully meshed, pawls I10 and I14 have been lifted clear of the small teeth on their respective ratchet wheels, which allows the gear and ratchet wheel combination .to be reset or restored to its normal position wherein long tooth I66 contacts pawl I10, by power generated through unwinding of thetwo springs I66. Stop screws I62 and I68, mounted on bracket I64, prevent pawls I10 and I14 from being lifted clear of the long teeth I66 and I86.

Since each gear I56 is, in its respective consecutive order, in mesh with teeth I2I on main shaft I01, at the time it is reset or restored, the power generated through unwinding of the two springs I66, likewise rotates the main shaft I01, and correspondingly advances the film.

As main shaft I01 is so moved, to so advance the film, spring tension is built up in spring I25, which would immediately restore shaft I01 to its original position, if a locking and centering lever were not provided. This lever is shown at I65 in Figs. 13, 15, 23 and 24. It is pivoted at I66, possesses a single tooth I61 engageable with toothedportion I2I of main shaft I01, and is normally held against adjustable stop screw I66 by spring I66. Solenoid 200 is capable of locking and centering main shaft I01 in any position, when movement of its plunger 20I, pinned at 202 to locking and centering lever I65, causes single tooth I61 to engage with toothed portion I2I of main shaft I01.

Each locking lever I65 is actuated by its solenoid 200 to lock and center the main shaft I01 between forward. movements of the film caused by successive resetting of the storage units; and also to lock and center the main shaft I01 for display of the final total. De-energization of solenoid 200 permits the film to reset by action of spring I26 revolving shaft I01 until stop arm II2 strikes stop pin II5.

In Fig. 34 a wiring diagram is shown illustrating operation. The mechanical details of the structure shown in Fig. 34 are not intended to represent an actual construction, but merely to present a general view of the operating functions in connection with the wiring diagram.

The votometer is controlled by a device termed a selector, covered by an application filed June 3, 1986. The complete wiring of the votometer and the selector is disclosed in my application on the system itself filed May 4, 1936. In Fig. 34,

herein, the selector and wiring, as well as the member's voting units, are sufficiently illustrated to describe the operation of the votometer, but the other applications may be referred to if so desired.

Three voting units are indicated at a, b and c. Votingunit a is in the first voting division and connected to the first contactors in division A of the selector, and divison A of the selector controls the first storage units, aa, ac, and aa, re-

spectively, of the aye, not-voting and naysections of the votometer. Voting unit I) is in the second voting division, and connected to the first contactors in division B of the selector, and division B of the selector controls the second units, bb, bb and DD, of the three said votometer sections. Voting unit 0 is in the third voting division, and connected to the first contactors in division C of the selector, and division 0 of the selector controls the third storage units, cc, cc, and cc, of the three said votometer sections.

The voting units a, b, and c are connected to positive battery with their respective blades 208 resting on not-voting contactors 204, and, as

drawn, will operate the storage units of the mid-' dle or not-voting section of the votometer. If blades 208 were thrown to the right, they would operate the storage units of the left or' aye section of the votometer. If thrown to the left, they would operate the storage units of the right or nay section of the votometer. But in all cases operation of the votometer storage units would accur only while the selector wipers 205 were revolving and thereby completing the circuits to the voting units a, b, and 0, etc.

All selector wipers 205 are arranged to move together. Those in selector divisions A, B and C control the simultaneous storing of impulses from three groups or divisions of vmembers. Wiper 205 in selector section E controls the storage unit reset and film advancing solenoids I52, I53 and I54, and the locking and centering sole hold 200, in each section of the votometer, while the wiper 205 in selector section F controls the projection lamp e in each section of the votometer. Wiper 205 in selector section Gcontrols operation of the selector driving motor 205 and its brake release solenoid 201.

When a vote is to be taken switch L is closed, as drawn, whereupon current from positive conductor 20%? passes through switch L to wiper 205 of selector section E, and to contactor 209 of selector section F. From selector section E current on contactor tit passes over conductor 29 I to the three locking and centering solenoids 200; and

.current from-wiper 205 of selector section F passes over conductor 2i 2 to the three project ing lamps c; and since lamps e and solenoids 200 are connected to negative conductor 2W, all three projecting lenses 81 display zero totals from films locked and centered in that position, as the mem-, bers commence to vote.

For continuous totalization while the members are voting, presiding omcers switch t is closed, which energizes bralre release solenoid 201 and operates selector motor 205, so the wipers revolve continuously. As drawn, current from conductor 200, and through the three contactors 204, reaches the first contactor in the N--V or not-voting series of contactors, in each selector division A, B and C. As the wipers 205 in selector divisions A, B, and C wipe the first contactors in their respective paths, current proceeds over conductors 2, H5 and 2IB, to simultaneously energize solenoids I80, it i and I82 in the center or not-voting section of this votometer. Thereafter the solenoids I80, NH and I82, of all three sections of the votometer, receive further operating impulses from other voting units, through further rotation of wipers 205 in selector divisions A, B, and C,

as said wipers pass over other energized contactors in their paths. With a selector of three divisions, such as drawn, three impulses are always simultaneously stored, and then three more, etc., etc. It happens that with the three voting units a, b, and c drawn in the, not-voting position, all storing solenoids in the not-voting section of the votometer would be simultaneously operated as wipers 205 contacted the first contacts in their paths, but if voting unit switches a, b and 0 had been in three different positions, one storing solenoid in each of the three sections of the votometer would have been simultaneously energized.

When the wipers 205 have completed approximately half a cycle, those in selector sections E and F leave contactors 2H) and. 209. The pro- Jection lamps e are immediately extinguished, and the locking and centering solenoids 200 are released. While wiper 205 of selector section E passes through open space 2I1 and the solenoids 200 are de-energized, nothing happens if the films had been registering zero totals, but if the films had been registering votes they would have been reset to the zero position, as locking and centering .levers I95 released their respective main shafts I01.

As selector section E wiper 205 further advances after allowing the films to be set, successive contact is established with contactors 2I8, 2I9, 220, MI, 222, 223, and 2), and in each case the wiper establishes the new contact before breaking the old contact, so the locking and centering levers I95 cannot release their main shafts I01 while the films are being stepped into their new positions. At 2I8 solenoids 200 lock all main shafts I01 in the normal or zero registering position. At 2l9 all three I52 solenoids are operated, which permits all three aa storage units to engage their respective I01 shafts and move their respective films forward sufilciently to register the votes controlled by selectordivision A. At 220 solenoids 200 look all main shafts I01 with selector division A totals registered. At 22I all three 553 solenoids are operated, which permits all three 122) storage units to engage their respective shafts H11 and move their respective films sufficiently to register the additional votes controlled by selector division At 222 solenoids 200 look all main shafts I01 with selector division A and B totals registered. At 223 all three l5 l solenoids are operated, which permits all three cc storage units to engage their respective shafts H01 and move their respective films forward sufiiciently to register the additional votes controlled by selector division C. At Elli solenoids 200 look all main shafts Hi1 with selector A, B and C totals, or the final totals registered; and at this time wiper 205 of selector section F establishes contact with contactor 209, lighting all three projection lamps c to display the totals.

With continuous totalization this cycle is continuously repeated; new totals being stored while old totals are being displayed; and the old totals being released as selector section E wiper 205 passes through space 2I1. Switch '4, which is closed to secure continuous totalization, could be opened in the middle of a selector cycle, but nevertheless all wipers 205 would continue to revolve until they completed their cycle of operation, because selector section G wiper 205 would hold the selector motor and brake release solenoid circuit closed by riding on contactor 224, permitting current from positive battery to pass through motor 206 and solenoid 201, and reach negative 2I3, through conductor 226, wiper 205, contactor 224 and conductor 221, instead of following the flrst path through switch 4. After the selector has stopped, and the final total has been sufliciently displayed, switch L is opened, extinguishing all projection lamps e, and deenergizing all solenoids 200, which resets all films or their equivalents to zero.

, When only a single totalization is required, the selector wipers 205 are operated for one revolution only, by closing switch 5 temporarily. Current on conductor 225 reaches negative 2I3,

through wiper 205, contactor 225, switch 5 and conductor 221, operating motor 206 and brake release solenoid 201. Motor 206 and solenoid 201 continue to operate, for the balance of one cycle of the wipers 205, even after switch 5 has been opened, because wiper 205 of selector section G, by riding on contactor 224, completes the circuit from motor 206 and solenoid 201, through conductor 228, and conductor 221, to negative 2I3. When G wiper 205 leaves contactor 224 at the end of one revolution, the circuit to motor 208 and solenoid 201 is broken, because the opening of switch 5, which is preferably of the momentary contact type, left contactor 225 electrically disconnected. After the selector wipers 205 have total has been sufliciently displayed, switch L is i opened, extinguishing all projecting lamps e, and

de-energizing all solenoids 200, which resets all films or their equivalents to zero.

The connections of the indicator lamps 98 of the indicator board of Figs. 6-8 are shown in Fig. 34 in circuit with the control units it, b, c, in such relation that operation of any of the veting units to aye or nay position will cause an indication thereof in the proper positions adjacent the respective members names on the indicator board 15. Thus, by the arrangement of my invention indication is made not only of the totals of the aye and nay votes cast and of the number of members not voting, but also of the particular vote, aye or nay, of each voting member. The combined result of the individual and total indications is a full and detailed account of the voting in respect to any one issue.
